"Always listen to experts. They'll tell you what can't be done and why. Then do it" - Robert Heinlein
As one of reportedly fewer than 10 people ever to be invited to study for a PhD at Cambridge without a prior undergraduate degree, Jane Goodall was promptly told by "experts" there that all her field work on chimpanzee behaviour was wrong, and that she should not anthropomorphise them with names, still less assign them thoughts, personalities and emotions.
Today, we know that she was right and they were wrong.
